Introduction to Heat Sealing

The book explains concept and principle of heat sealing and the correlation between molecular properties and seal performance.

Theoretical Aspects and Mechanisms

First, theoretical aspects of heat sealing and the mechanism involved in seal formation are discussed.

Test Methods and Quality Evaluation

Then different test methods for evaluating seal and hot tack performance and quality are reviewed.

Sealant Materials in Flexible Packaging

Different common sealant materials in flexible packaging are discussed including multiphase and bioplastic sealants.

Processing Conditions and Material Characteristics

Effect of processing condition and material characteristics on seal and hot tack performance of sealant materials are reviewed.

Mathematical Models for Optimization

Mathematical models are presented as powerful tools to optimize sealing condition in order to balance production cost and seal properties.

Practical Applications

Finally, practical examples of sealant design are introduced in food and industrial packaging.
